  1. DIGITAL SIGNAL PROCESSING Introduction

  2. Course information

  3. Course information(C0ntd..)

  4. Discrete Time signal • Sequence x[n] as opposed to continuous time signals x(t)

  5. Discrete in Nature • Population statistics • Stock market indices

  6. Sampled continuos time (analog) signals • Example • Speech

  7. Applications

  8. Speech Processing Original speech High pass Down sample Up sample Low pass

  9. Image Processing

  10. Video Processing General Concept: Object 1 Motion Analysis Object 2 Video Synthesis Applications Analysis

  11. Discrete-Time System y(n)=T{x(n)}

  12. Why DTSP? • Discrete Time Signal Processing of Continuous Signals x (n) y (n) y(t) x (t)

  13. WhyDTSP? Digital Signal Processing (DSP) is derived from DTSP y(n) y(n) x(t) x(n)

  14. Discrete Time Signal

  15. Where Not?

  16. DSP COMPONENTS • Converting analog signal into digital sequence. • Performing all signal processing operations in digital in digital form. • If necessary converting the digital information back to analog signal. • A TYPICAL DSP SCHEME Analog Filter ADC DSP Processor DAC Analog Filter
